On my laptop, I use mutt with postfix for sending e-mails, and fetchmail for
receiving them. Postfix is setup to relay mails through gmail. I am the only
user on the computer and all mails originating from the computer are sent
from my account.
A limitation of the present setup is that it sends e-mail only from a
particular gmail account. I have, like most people these days, about four of
different e-mail accounts that I like to use for different purposes. I would
like to set up mutt and postfix in such a way that I could use these various
accounts for sending mail. I have set up mutt profiles for different
accounts. With that mutt is able to send mails with different "From:"
headers.
But since all mails are passed on to postfix from my user account, they are
all treated as coming from u...@localhostname. Postfix ignores the From
address put by mutt, and treats it only as coming from
u...@localhostname.it then delivers the mail using only sasl password
authentication from one
account which has been set up to handle all general mail. The sasl password
authentication file also has details for other accounts but since postfix
does not treat the mail as coming from those account, it does not use the
sasl password authentication for them. In other words, since all mail is
treated as coming from u...@localhostname, they go through the same sasl
password authentication, and therefore are sent as coming from the
same sender account.
I do not know if I have been able to make myself clear. I shall be more than
happy to clarify again if I have not been able to.
I am appending my /etc/postfix/main.cf
I shall be happy to provide (samples of) other configuration files, if
necessary.
I shall be grateful if anyone could point me to a useful guide on the issue.
